SPECIFICATION forming part of Letters Patent No. 261,479, dated July 18, 1882,

Application filed January 27, 1882. (No model.)

To auw/1.0m it may concern:

Be it known that I, JOHN A. PORTF-R, of

" St. Louis, Missouri, have made a new and useful Improvement in Car-Couplings, of which 5 the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in Which Figure 1 is a plan of the improved coupling;

1o Fig. 2, a horizontal section taken on the line :c w of Fig. 4; Fig. 3, a vertical section taken on the line yy ot' Fig. 1, and Fig. 4 a side elevation. I

The same letters denote the same parts.

15 I have heretofore madevan improvement in car-couplings wherein the coupling is effected by means of a double-headed bolt, the drawheads being chambered outto receive the holtheads, and the bolt, after its insertion in the zo draw-heads, being held therein by turning it around so as to bring the shoulders 'of the heads to bear against shoulders within the draw-head chambers, and the bolt being provided with a handle by means ot' which the 25 bolt can be manipulated. In the construction referred to the handle of the bolt, after the coupling is accomplished, is turned downward, coming between the opposing drawheads, and the anges surroundingthe mouths 3o of the latter project uniformly around the mouths-that is, the iange above the drawhead mouth projects equally with the flange' aie bearing against each other, are the aim of the present improvement, which is supplementary to the'one referred to, and as follows: 45

A represents the coupling. The draw-heads B B are chanibered out at b b, and are proi vided willi the shoulders b', and the mouths 1,2 are elongated laterally, as in the original construction. .The coupling-bolt O is also, as 5o before, furnished with the iiattened heads c c and the handle l), and the coupling and nncoupling are effected in substantially the saine manner. In place,.ho\vever, of' makingthe anges around the draw-head'mouths to 55 project'equally above and beneath the inonths,. the draw-heads are made so that thebolthandle shall swing freely to and from a vertical position to a horizontal, even when the opposing faces of the draw-heads are hearing 6o against eachother, as seen in the drawings,

Where the anges b3 b3 project farther than the flanges b4 b, and suliiciently to provide a space, b5, in Which'the handle D can be moved so as to be able to withdraw the bolt from 65 JOHN A. PORTER.
